Abstract
An axle lubrication structure comprises a spindle and a bearing assembly thereon, which is characterized in that an oil channel is provided in the spindle and is provided with an oil inlet and a group of branch oil channel outlet communicated with each bearing; the oil inlet and the oil outlets are annular oil grooves. The internal oil channel in the spindle can greatly save space. The main oil channel distributed on bearing base in prior art is changed to be arranged on the spindle to reduce the volume of the bearing base, save space, reduce weight and keep the volume of the spindle. The internal oil channel can reduce the weight of the axle and realize lightweight design.
Description
Technical field
The utility model relates to a kind of class lubricating structure, particularly relates to a kind of lubricating structure of balance shaft of engine.
Background technique
At present, the general axis class is lubricated all to be to adopt the bearing saddle bore oil duct to come fuel feeding, in order to lubricating bearings.It is mainly constructed is that a main oil gallery is arranged on the bearing support body, communicates with the branch oil duct of each bearing support, and lubricant oil flows through from main oil gallery, and the branch oil duct from each bearing support enters the bearing contact position, is lubricated.The space of bearing support body is increased, increase the space and the weight of complete machine, not satisfy lightweight requirements.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the existing axle class lubricating structure to provide a kind of class lubricating structure, and it is simple structure, reliable operation not only, and has realized light-weight design.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of class lubricating structure, comprise main shaft and on one group of bearing, it is characterized in that: main oil gallery is set in main shaft, and main oil gallery has a filler opening and one group of branch oil duct oil outlet that leads to each bearing.
Reliable in order to guarantee oil-feed, described filler opening is an endless oil groove.
Fuel-displaced reliable in order to guarantee, described oil outlet is an endless oil groove.
Described main oil gallery can also be along the spindle axis setting.
Good effect of the present utility model: on the basis that guarantees bearing lubrication, change oil supply gallery position is transferred to oil duct on the main shaft.The external shapes such as diameter length of axle are not made change, the main oil gallery of opening at the bearing support body is originally transferred to axle come up.Machine oil comes out from the cylinder body main oil gallery, at first arrive one apart from the nearest bearing socket of main oil gallery, axle is opened an oilhole that radially connects at this circumferencial direction, lubricant oil enters axle, open the axial long hole of a vertical perforation with radial hole at the center of axle, open the branch oil duct in other each positions of bearings then, the lubricant oil of axle central oil passage is guided to each minute oil duct, enter each position of bearings and be lubricated.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model organigram.
Among the figure: 1. main shaft, 2. main oil gallery, 3. filler opening, 4. oil groove, 5. oil outlet.
Embodiment
As shown in Figure 1, a kind of class lubricating structure, comprise main shaft 1 and on one group of bearing, main oil gallery 2 is set in main shaft 1, main oil gallery has a filler opening 3 and one group of branch oil duct oil outlet 5 that leads to each bearing.Reliable in order to guarantee oil-feed, described filler opening is an endless oil groove 4.Fuel-displaced reliable in order to guarantee, described oil outlet is an endless oil groove.Described main oil gallery is along the spindle axis setting.
The utility model working method is, lubricant oil enters the bearing socket at main shaft 1 place from the cylinder body main oil gallery, enters an inner chamber main oil gallery 2 by oil duct main shaft 1, arrives each minute oil duct oil outlet 5 again, and lubricant oil flows out the bearing socket at lubricated place thus.Owing to adopt built-in oil duct, save the space greatly.The main oil gallery that need be arranged in the bearing support body is originally transferred to above the main shaft, reduced the volume of bearing support body like this, saved the space, alleviated weight, the volume of main shaft does not change simultaneously, and because oil duct is opened in inside, the weight of axle itself also alleviates, and has realized the light-weight design of killing two birds with one stone.
Claims (4)
1, a kind of class lubricating structure, comprise main shaft and on one group of bearing, it is characterized in that: main oil gallery is set in main shaft, and main oil gallery has a filler opening and one group of branch oil duct oil outlet that leads to each bearing.
2, axle class lubricating structure according to claim 1, it is characterized in that: described filler opening is an endless oil groove.
